Immune-Regulating Drug Improves Gum Disease in Mice

A drug that has life-extending effects on mice also reverses age-related dental problems in the animals, according to a new study published today in eLife.

Periodontal disease, also known as gum disease, is a common problem in older adults that causes painful inflammation, bone loss and changes in the good bacteria that live in the mouth. Yet there are no treatments available beyond tooth removal and/or having good oral hygiene. The findings suggest that treatments targeting the aging process in the mouth might help.

Rapamycin is an immune-suppressing drug currently used to prevent organ rejection in transplant recipients. Previous studies in mice have also suggested that it may have life-extending effects, which has led to interest in studying the drug’s effects in many age-related diseases.
